Hi Dave, Thank you for your reply.It means a lot to me. By the way, is it possible to have the analysed data on the study you mentioned regarding the solderability "conditioning " ? Can we establish the correlation of solder shelf life based on y

DC powered Power-up and ageing burn-in equipment, preferably non-product specific, starting from room temperature down to -41 degrees celcius and up to +71 celcius at a rate of 7 celcius per minute. But anyone who could suggest a manufacturer would b

Can someone explain what ageing means in terms of chip caps. Capacitor vendors state 7% per decade hour or 2-5-1 per decade hour. What does this mean? I think capacitor values lower over time but what is a decade hour. Thanks, Chris

Tantalum caps degrade over time. You should not be seeing "chipped-off & cracks" regardless of the age. This should not be a shelf-life issue, unless you are storing them in an aquarium. Tell us the story. Solderability is a shelf-life issue and

It's possible that N2 vogued at the dawn of the NC age. Once practitioners jiggered their profiles and more importantly, paste suppliers developed a decent product; the demand for inerts declined. Day-off sound like a fair trade.

What is new in the age of the Internet? Once new meant 3 or 4 weeks, now it means 3 or 4 days, if not 3 or 4 hours. Jeff Ferry

Fyi, I just came across this the other day and you should look GSC, info@gogsc.com. They have been around for ages and do a great job for Lucnet.
